Two reciprocatingslides 2 and 3 forifeed- 'ingpastcboard strips or blanksand the pa-i per-covering strip for the bodies: or sides of {boxes are operatedby lateral pins on -a vi-'.

brating arm 4, which is connected by a rod with an; arm 5, l1aving a roller held by-a spring6 in engagement withthe earn 9. The

' under side withtlieipinon arm 4 nearest its J slide 2 is connected directly bya lug on its fulcrum. The slide 3 is provided on its upper side [with lugs, 7 in the path of theother pin on said arm so that during the initial movement of the slide 2 forward the slide 3 will remain. at rest. These slides'are grooved I or flanged lengthwise on llll'll" upper I sides and provided with springs 8 and 9 to hold I the pastlioard and paper blanks or strips in place thereon and to carry them forward therewith between the guide-rollers when The body blanks or strips are previously cut jacent bearing of the shaft 1.

to the required length and supplied by hand, one at a time, to the slide 2, or byslight modification of the feeding mechanism they may be out to length as they are fed to the machilne from a continuous'strip wound ona ree 1.1 is a reel on which is wound the paper- 'covering strip and from which it passes between rollers 12 andaround guide-rollers 13 to the slide 3. The lower roller 12 is supplied with paste from a box 14 by a roller 15.

Referring to Figs. 9 and 10 in connection with Figs. 2 and 3, the shaft Z passes at its inner end'loosely through a sleeve 16, formed at one end with an external collar, to which is secured a sleeve 17. The sleeve 16 is made to turn with the shaft Z by a pin or key 43, secured in said sleeve and engaging a longitudinal groove in said shaft, as shown in Fig. 10, or by other suitable means. The sleeve 17 is longitudinally slotted on op osite sides and is formed at its outer end wit. an external flange fitting into a flanged ring 18, by which it is revolubly connected with the ad- In the annular space between'the'two sleeves 16 and 17 is loosely fitted an axially-movable sleeve'19, which serves as a form formaking the bodies or sides of the boxes. It is connected by screws or pins passing through the slots in the sleeve 17 with a ring 20, loosely fitting in an internally-grooved ring 21, thus permit ting the'sleeves 16, 17, and 19, with the ring 20, to turn with the shaft Z, while'the ring 21 does not turn. The ring 21 is pivotally connectedwith one end of a bell-crank lever 22, the opposite end of which is provided with a roller engaging with a groove in the face of cam lc, as shown in Figs. 2 and 5.

For holding the advance ends of the pasteboard strips or blanks on the body-forming sleeve 19 while it makes a revolution and wraps the strip or blank around it the clampinghead a is provided with an inwardlyyielding point 23. This point IS carried by a block which is loosely fitted in a recess in the head n and a notch in the end of sleeve 19 and is mounted, as shown in Figs. 10 and 11, on the free end of a spring 24, attached to the shaft Z in a longitudinal recess therein.

is an elastic presser-foot, made of rubber or other suitable material and carried in one end of a lever 26, the opposite end of end of the sleeve 19 when the latter is in 'posil tion for winding a pasteboard strip or blank thereon' i I have shown the point 23 and the s ring 24- as inwardly yielding. Bymechanica change these parts may be made critwardly yielding and grasp the blankfrom the outer side rather than the inner s de. The essential featureis that the point 23 reciprocates on a plane of the axis of rotation and that such reciprocation is caused by a part moving over the axis of the rotatin parts.

28 is a presser whee carried by one end of an angular lever 29, the op )osite end of which is provided with a roller held by a slpring 30 in engagement with the cam he wheel 28, as shown in Fig. 8, is com )osed of two parts 31 and 32. The part 31. has a plain smooth face with a groove or recess in one side to receive the projecting edge of a bottom blank, as shown in Fig. 11. The part 32 is slightly beveled on the side next to the part 31 and extends beyond its periphery. It is yieldingly held against'the )art 31 by a spring 33 (shown in Fig. 7 to al ow for variations in the thickness of the bottomblanks and to avoid tearing the paper-covering strip by which the bottoms are attached. to the bodies of the boxes.

'34.is a movable knife working with a stationary knife '35 and carried at one end of a lever 36, the o posite end of which is provided with a roller held by a spring 37 in eugagement with the cam j. These knives are located between the slide 3 and the guiderollers 10 for cutting off the paper-covering stri at the proper points.

he lever 26 is provided with a twisted angular spring 38 for turning the paper-covering strip inward over the edge of the pasteboard body, as shown in Fig. 12.

39 is a sleeve fitted upon and turning with the shaft m, which is movable endwise therein. It is internally recessed, as shown in Fig. 3, to receive the spring q, and is provided at its inner end with a flanged head 40 for pressing the inturned edge of the pa )er covering-strip against the bottom, shown in Fig. 12. The head 40 is recessed to receive the clamping-head 0, as shown in Fig. 9. At its outer end the sleeve 39 is formed or provided with a grooved collar engaged by the forked end of a bell-crank lever 41, the opposite end of which is provided with a roller engaging a groove in the face of the cam c.

The clamping-heads n and 0 are recessed to receive elastic'pads in theiropposim faces, as shown in Fig. 10, to more effectively hold the bottom orend blanks between them.

In the machine herein shown and described as illustrating the invention the gear and pinion b and r are so proportioned that the shaft l, with the clamping-heads n and 0 and the forming-sleeve 19, will make six revolutions to one revolution of the main shaft A; but this proportion may be varied according i 2 5 gether by came to the to the number and order of the operations v which'tlie-machine is'designed to perform.

The

zo f head n isthenthrust inward by cam f into position to clamp. said blank between it and the opposing head 0,-as shown in Fi 9. Both the clamping-he'adawith the, bl an held be-' tween them, are thereu on moved back toibrming-sleeve 19', as

shown in FiglO. Simultaneously with or immediately following the last-mentioned operation the slides 2 and 3, aremovediforward by the cam g, carrying the inner ends of a obody-blank and the covering-strip between theguide-rollers 10, the body-blank moving in advance of the covering-strip,'which. being supplied with. paste on the lower side is stuck tothe upper side of the body-blank as 3 5 itpasse's between said rollers The advance end of :the body-blank passing betweenthe sleeve 19 and the foot-525 is momentarily pressed down uponth e point 23, as shown in Figs. 6 and 10, by the engagement of the 412 shorter projection on cam h w' h the roller on lever-26. 1 The spring 38, thelower end of I which strikes the-sleeve-.19,-yields upwardlyto permit the-depression of the foot in the foregoing operation. The body-blank, with 5(the. coveringstrip pasted thereto, being caught and held by the point 23, is wrapped around the sleeve 19 'bytherotation of the shaft Z. At thesame time the roller on lever '29 dropping'into a depression inthe cami 5o permits the spring'30'to carry the wheel, 28

toward the sleeve 19, holding said blank: and the covering-strip witha yielding pres- ;sure against said sleeve and turnin one edge of the covering-strip inward over the edgeof the bottom orend blank, as shown in 11;

The forming-sleeve "1 9 is thereupon withdrawn from'the head 0 end of the box. lied With a body-blank cut to the requiredas shown in Figs. 9 and 10, and the sleeve 19, is withdrawn by the cam 7c to the position'in' In short, various changes and modifications by the. cam 7c,- and the spring 38 is depressed by the longer projection on-the cam 7r, as shown in Fig. 12, while'the clamping-heads make another complete revolution, thereby turning the edge of the covering-strip inward 7 over the edge of the body-blank atthe open Immediately following the foregoing operation the sle ve 19 is moved back by the cam 7c toward the head 0 to turn the covering-strip inside of the box, as shown in Fig. 13; .While the last two preceding op erations are taking place the head 40 is thrust inward by the cam a, pressing the other'in turned edge of the covering-strip against and sticking it to the bottomof the box, as shown in Figs. 12 and13. The icams e and f now. permit thejsprings p and q to separate the clamping-heads n and 0, the head 40 is withdrawn by the cam cto its original. position whichit is shown in Fig. 12, thereby releasing the finished=box, whiehis stripped from v the sleeve 19 by the sleeve 17 and allowed to drop from the machine. Theforegoing oper- 7 9 atlons being repeated as explained, a complete 'boxor cover is made to each revolution of the main shaft a, y i p By varying the shape of the clampingheads at and o, the forming sleeve 19, the' 5 presser-wheel 28, and the head [40 the mar chinemay be made to produce polygonal boxes, having any desired number of plain I sides with rounded corners without change in principle or mode of operation. g

The covering-strip is usually composed of two bands of-paper, and by slight and ob-.-. vious modifications in the feedinginecham ism these bands may be wound on separate reels-and pasted together as they are fed to the machine. The covering-strip may also be cut'to therequiijed lengths and these lengths, like the body b lanks, fed to the machine one at a time by hand or otherwise. 'l hejbody-blanks, on the other hand, may be suppliedin rolls and, like thecovering-strip,

cutto length as they are fed to the machine. They .may'also bemade of thinner stock and wrapped a number of times aroundthe forming-sleeve 19 to produce a body of the requisite thickness and; stability. The terms body-blanks and f covering-strip as employed in the claims are intended to include i such blanks and strips whether out to length as they are fed to the machine orjbeforehand.

in the details of construction and inthe 'arrangement of component parts of the machine may be made within the spirit and intended scope of'the invention.
